Dispersion at natural pH under sonication led to even worse results, likely due to the zeta potential of silicates and iron oxides, combined with the enhanced mixing caused by ultrasound, which ...

Silver discolours and darkens when it is exposed to sulfur-containing gases such as hydrogen sulfide ... ethanol instead of water to make up the slurry (Long 1999) or a mixture of ethanol and water ...

Now they've also uncovered something even older - evidence of what could be the earliest making and use of iron. Present-day Turkey is one of the earliest known regions where iron was mined ...

This process is long and comparatively expensive, because the mixture of oxygen or oxygen-bearing substances is not made intimate with the iron except by long stirring, which is not only skillful ...

In a translational mouse model of T1D, a Topas particle mixture comprising five different peptide-coupled TPCs, significantly reduced the frequency of hyperglycemia onsets compared to control ...

The converter is a wrought-iron pot, lined with fire-clay. In the bottom of it was introduced a mixture of 169 lbs. of crude nitrate of soda, 40 lbs. of silicious sand, and 20 lbs. of air-slaked ...

Severe iron deficiency anemia can cause hair loss. This includes androgenetic alopecia or pattern hair loss. Iron deficiency anemia occurs when a person does not have enough iron in their system.
